چکیده
Abstract Ethylenediaminetetraacetic acid disodium (EDTA) can form stable complexes with many metals. To improve the leaching rate of gold and consumption thiosulfate, EDTA ammonia were combined copper ions to a copper-EDTA-ammonia-thiosulfate system. Electrochemical methods used study effect ion, EDTA, polarization voltage. The results showed that increasing concentrations ions, promoted dissolution gold, which changed from electrochemical control diffusion after adding EDTA. order influence was thiosulfate > ion. pure experiment in EDTA-ammonium-copper system higher than EDTA-copper-thiosulfuric system, thus achieving synergistic leaching.

Modeling the transport of metals with rate-limited EDTA-promoted extraction and dissolution during EDTA-flushing of copper-contaminated soils.
EDTA-flushing of artificially contaminated soils enhanced Cu extraction but also induced mineral dissolution simultaneously. The mobilization and transport of these metal-EDTA complexes was investigated with column experiments. A quantitative transport model was proposed for simulating the experimental breakthrough curves of Cu, Fe, Al, and Ca. The rate-limited EDTA-promoted extraction and diss...
متن کاملElectrochemical ammonia compression.
Every year a large amount of ammonia is mechanically compressed with a low efficiency (∼65%) as an environmentally friendly chemical for fuel storage, transportation, food preservation and air conditioning. Electrochemical compression with a high efficiency (93%) offers an opportunity for substantial energy savings. But ammonia is never considered electrochemically compressible because of the k...
متن کاملThe aluminium - copper - gold ternary system
Despite Au, Al and Cu being individually very wellknown elements, their ternary phase diagram has not been studied in as much detail as those of many other Au-containing ternaries. Here we review what is known, and consider the prospects for technological exploitation of some of the ternary compositions. The components of greatest interest in Al-Au-Cu may be the β-phases, at least two of which ...
متن کاملPrediction of recovery of gold thiosulfate on activated carbon using artificial neural networks
Since a high toxicity of cyanide which use as a reagent in the gold processing plant, thiosulfate has been recognized as a environmental friendly reagent for leaching of gold from ore. After gold leaching process it's important for recovery of gold from solution using adsorption or extraction methods, One of these methods is activated carbon.The loading of gold from industrial thiosulfate solut...
متن کاملElectrochemical analysis of Shewanella oneidensis engineered to bind gold electrodes.
Growth in three-electrode electrochemical cells allows quantitative analysis of mechanisms involved in electron flow from dissimilatory metal reducing bacteria to insoluble electron acceptors. In these systems, gold electrodes are a desirable surface to study the electrophysiology of extracellular respiration, yet previous research has shown that certain Shewanella species are unable to form pr...
